An Egyptian court on Saturday upheld the life sentence against ousted Islamist president Mohamed Morsi in what is known as the Qatar espionage case.
There have been no explanations yet for the rulings and they can not be appealed.
The life sentence for Morsi is now final while the Court of Cassation canceled another 15-year prison sentence handed down to him. Morsi was Egypt's first democratically-elected president when he came to power after the 2011 uprising that toppled long-time leader Hosni Mubarak.
In 2014, Morsi and nine other senior officials were accused of "endangering Egypt's national security" after highly-classified documents were leaked to Qatar.
The Egyptian Court of Cassation issued a final ruling on Saturday, reducing Morsi's sentences in the espionage case from a combined total of 40 years to 25. In October last year, the same court had confirmed a 20- year prison sentence against Morsi for taking part inciting violence near Ittihadeya presidential palace in 2012.
Morsi was immediately arrested after the coup and Sisi has been the president of the country since 2013. The convicts, members of the Daesh branch in neighboring Libya, can appeal the sentences as they should go to a process of review by the Grand Mufti, Egypt's top theological authority, until November 25.
The defendants are charged with joining a terrorist cell in Egypt's governorate of Marsa Matrouh affiliated with the Libya Daesh militant group.
The court will give its final sentence against another 13 accused with the same charges in November 25.
The Egyptian government has been cracking down on the Muslim Brotherhood and its supporters since the ouster of Morsi, which left thousands in jail, and hundreds facing trials on a variety of charges.
